Mornay

Mornay Armstrong (1249-1298) was a noble of the Kingdom of Scotland. He was initially a leader of the Scottish rebellion against King Edward the Longshanks in 1296, but in 1298 he deserted to Edward in exchange for several estates in Yorkshire.

Biography
Mornay was from a family of Scottish nobles, and he was friends with Lochlan Murtagh, Craig Kavanagh, and Robert the Bruce. He was one of the Scottish nobles who decided to support William Wallace's rebellion against the Kingdom of England in 1296, seeking to gain more lands. At the Battle of Stirling, he led the Scottish cavalry in an ambush of the English archers from the rear, a move that won the battle for Scotland. However, he was one of the nobles who took part in the arguments over John Balliol's attempts to get Wallace to pledge allegiance to him, Wallace's plan to invade northern England, and whether or not to fight at the Battle of Falkirk in 1298. King Edward the Longshanks gave him estates in Yorkshire in exchange for his betrayal of William at Falkirk, and William lost many of his friends in the battle. In revenge, William Wallace rode into his bedchambers in the middle of the night on a horse and killed Mornay with the swing of a mace to the head after Mornay woke up from a nightmare.
